Lutz,
The purpose of the calibration? indeed to remove the jump in the signal when it switches to harmonic mode.
A jump in the noise is unavoidable as the signal path loss increases due to harmonic mixing.
The bumps in the noise floor are unavoidable as the internal signal path is far away from 50 ohm at these high frequencies.
